4 Claims. (Cl. 242 55.2)

My invention relates to improvements in paper roll dispensers of the type wherein a jet of air is utilized to blow the free end of the paper strip over the roll, whereby it may hang in a convenient position.

In previous devices of this kind the air pressure was developed manually and would sometimes be of insufficient force to carry the free end of the paper over the top of the roll, consequently the operating means had to again be actuated before the free end of the paper was exposed to view or presented for removal from the remainder of the roll.

The principal object of the device is to provide a simple secondary means for carrying the free end of said paper strip over the roll.

Referring to the drawing:

Fig. 1 is an elevational view of the invention, with a part of the paper rollmandrel removed to show the several air jets.

Fig. 2 is a sectional view taken on the line 2-2 of Figure 1.

In the drawing like characters of reference indicate corresponding parts in each figure.

The numeral l indicates a casing consisting of a back wall 2, side walls 3, a hood 4 and a bottom wall 5. Within the casing a bellows 6 is provided which makes use of a portion of the back wall 2 as its rear wall and'ha enclosing side walls 8, indicated in Figure l in dotted lines, top and bottom walls 9 and I0 respectively and an inclined front wall I I.

The front wall I is provided with one or more upwardly inclined-air jets I3 and one or more horizontal passages l4 are formed upon the top wall 9 which are open to the rear of the bellows and discharge through jets l5 which are formed in the front wall. A slot H is formed transversely of the front wall at its intersection with the bottom wall through which the base of a bellows flap or piston l9 projects, the lower extremity of said flap is suitably weighted to maintain the flap normally in contact at its upper end with the back wall 2 and also to provide a lever 2| by which the flap is moved to sweep the air in front of said tab as indicated by the arrow X and through the upwardly inclined jets l3. The counterweighting of the flap It! by the lever 2| serves to restore the flap to normal position as indicated by the arrow Y and sweep the air at the back of the flap outwardly through the horizontal jets l5. I

Supported from the casing l is a mandrel 23 upon which a roll of paper 24 is adapted to be placed, the paper roll is so held that the line of 56 a the other of d j s in perforations 25 dividing sheets is above the jet l3.

When the lever 2| is pressed back, a current of air is discharged through the jet |3 which lifts the free end of the paper strip forming the roll and normally throws it over the top of the roll and permits said free end to hang down in a convenient position for detachment. Assuming that insuificient pressure was applied to the lever to carry the paper over, the flap on returning to its normal position will cause an outflow of air through the discharge jet I5 in a horizontal direction. This air discharge is sufiiciently delayed to permit the free end of the paper to be well raised with respect to the top of the roll so that the air flow from the jet IE will get under the strip and into the bight of the paper, indicated as Z in Figure 2, and carry the free end of the strip outwardly between the rolland the hood 4, thus assuring the proper presentation of the free end of the paper even though the air pressure delivered through the jet I3 is below the normal requirement.

The hood 4 also serves to COIlfiIle the air from the jet 15 so that its force must be utilized between the free end of the strip and the top of the roll.

What I claimas my invention is:

l. A paper roll dispenser comprising a support,- a. mandrel carried from the support adapted to receive a roll of paper with its free end depending between said roll and the support, a double acting blower having a piston and two air jets, one of said jets being in communication with the blower space on one side of the piston and the second of said jets being in communication with the blower space on the opposite side of the the roll into connected piston, one of said jets being disposed to discharge air to initially lift the free end of the paper as the piston is moved forwardly and the,

second jet being disposed to discharge air to drive the disturbed free end transversely across the roll as the piston moves rearwardly.

2. A paper roll dispenser comprising a double acting blower having a piston and a discharge jet from each side of the piston, said piston being adapted to rest normally adjacent one end of its stroke and to be manually operated away from its normal position, a mandrel supported adjacent said jets, said mandrel being adapted to receive a paper roll divided into connected strips, one of said jets being disposed to deliver air tangential to the roll to lift the free end of the paper roll as the piston is moved forwardly arranged to discharge air to carry the disturbed free end transversely across the roll as the piston movement is reversed, and means for returning the piston to its normal position.

3. A paper roll dispenser comprising a double I receive a paper roll divided into connected strips,

one of said jets being disposed to deliver air tangential to the roll to lift the freeend of the paper roll as the piston is moved forwardly and the other of said jets being arranged to discharge air to carry the disturbed free end transversely across the roll as the piston is moved in th opposite direction, and means for returning the piston to its normal position and a hood spaced above the second jet adapted to direct the air from said second jet towards the mandrel.

4. A paper roll dispenser comprising a bellows body having a back wall, a front wall having an air jet and surrounding walls, a passage communieating with the interior of the bellows body extending from a point near the back wall forwardly to discharge air adjacent the front wall, a flap rockingly mounted within the body and a lever extending outwardly of the body to facilitate operating the flap, said flap being adapted to rest normally adjacent the back wall and to sweep the air between it and the front wall outwardly through the jet when the lever is manually moved and to sweep air between said flap and the rear wall through the passage a the flap returns to normal position, and means for supporting a paper roll in front of the air jet and the discharge end of the passage.
